Abstract

Lancing system comprising a needle and a lancing device The lancing device comprises a housing with a housing opening that is surrounded by a housing skin contact surface. A lancing depth reference element with a reference skin contact surface is adapted in such a manner that the reference skin contact surface at a reversal point of the lancing movement is in contact with the skin. The lancing depth is determined by the distance between the reference skin contact surface and the tip of the needle element at the reversal point of the lancing movement. The lancing depth reference element is in a stationary defined position relative to the reversal point of the lancing movement. The lancing depth reference element is adapted to stabilize the skin when pressed against the reference skin contact surface with respect to a skin deformation which occurs upon lancing of the skin.
